Rendering problem with Vegas 6.0

[seven_deuce offsuit]

I've been working with this software for a while now but since last week I noticed everytime I render a project in MPEG-2 format, I end up getting a MPEG-2 Movie file with no sound, which is not typical from the Windows Movie Clip file I've always gotten. The Movie Clip files have sound and I've always used the Batch rendering method to get both MPEG-2 and 5.1 surroud. But now, ever since I've been using that particular scripting method or the normal "render as" method I get an MPEG-2 video with no sound. Does anyone know why it's doing this? I don't remember doing anything different. And if this helps, those problematic videos open with Nero Show Time by default instead of Windows as before. I need help with this, I'd really appreciated it. Thank you.

Are you outputting an elementary video stream (i.e. just video) ?
Can you play back 5.1 material on your PC with audio ?

[seven_deuce offsuit]

Yeah, I can play 5.1 material on my PC. I have with my other videos that weren't affected and also with DVDs. But now for some odd reason when I batch render MPEG-2 with 5.1 audio, I don't get audio. I checked what type of file it was after it was rendered and it was a MPEG Movie file, which isn't giving me any sound. The ones that did give me sound after I rendered them were listed as either "movie clips" or "windows movie clips," which I'm not getting now.

Sounds like you have produced an elemntary stream.

What is the file extension ? (.mpg, .mpv etc)
What does g-spot say about it ? (latest beta version)

[seven_deuce offsuit]

It says it's a MPEG2 file.

[guns1inger]

what does it say about the audio content ? (And which version did you use ?)

[seven_deuce offsuit]

I'm using the 2.52 version and it didn't detect any audio. I've always thought it rendered the audio but I guess it didn't. How am I suppose to fix this?

[guns1inger]

Select the DVD NTSC (I assume you want NTSC, otherwise select PAL), which contains both audio and video streams. You can then customise it from the default 2 channel to use 5.1 channel audio. If you have a standard template that you use that you have modified yourself (I know I have a number of these) then check that to see if audio has infact been disabled.

The question I would ask is - do you need a program (or system) stream ? I cannot remember the last time I rendered to a combined stream. Certainly not when encoding for DVD.

[seven_deuce offsuit]

Oh ok, I think I see what I was doing. I was rendering the project as a DVD NTSC video stream (does that mean it'll render in only one stream?) and it wasn't giving me audio. I switched to DVD NTSC and I got my audio. Thanks. My templates were fine, I guess it was the type I picked to render.

Also, about that last thing you said about DVDs, are you saying it's a better idea to render in just DVD NTSC and maybe use something like DVD Architect to set your project template to 5.1 surround? I've been using DVD Architect to create DVDs, and I was wondering if you set the template of your project to 5.1 surround would it affect any video files in that project that already have 5.1 surround as a normal file?

[guns1inger]

If you are using Architect then it probably doesn't make much difference. I use Vegas to mix and encode 5.1 audio, but I render it as an AC3 stream. I edit video in Vegas, but frameserve it to CCE for encoding to a video stream. I then author in DVD Lab Pro. So I always render elementary streams
